Plants secrete purple acid phosphatases (PAPs) under phosphorus (P) shortage but the contribution of plant PAPs to P acquisition is not well understood. The goals of this study were to investigate comprehensively the transcription patterns of PAPs under P shortage in poplar (Populus × canescens), to identify secreted PAPs and to characterize their contribution to mobilize organic P. Phylogenetic analyses of the PAP family revealed 33 putative members. Read More
